Scientists Discover New Embryonic Cell Type that Self-Destructs to Protect the Developing Embryo

Scientists studying gene activity data of the early human embryo have discovered an overlooked type of cell which self-destructs within days of forming, as part of a quality control process to protect the developing foetus.

Heat-Damaged DNA in Food Linked to Possible Genetic Risks

Researchers have newly discovered a surprising and potentially significant reason why eating foods frequently cooked at high temperatures, such as red meat and deep-fried fare, elevates cancer risk. The alleged culprit: DNA within the food that's been damaged by the cooking process.

Unraveling the Link Between Environmental Toxins and Lymphoma in Dogs

Lymphoma is a common cancer in dogs, but unlike human studies, which have associated the disease with environmental toxins, little is known about how it originates in dogs.

Stimulating Cell DNA Repair Processes to Combat the Root Cause of Autism Spectrum Disorders

A new treatment option has been discovered for fragile X syndrome, which is the most common genetic cause of autism spectrum disorders and is defined by a hereditary repetition of certain nucleotides in the DNA sequence of the FMR1 gene. Researchers at Massachusetts General Hospital (MGH) carried out the study, which was published in the journal Cell.

Entry of Aging-Associated Enzymes into Human Genetic Material

An enzyme that controls aging and other metabolic processes accesses human genetic material to modify gene expression within the cell, according to a new study. Images of a sirtuin enzyme bound to a nucleosome, a tightly packed complex of DNA and proteins called histones, have been created by a team led by Penn State researchers.
